IMPLEMENT FOR TWISTING WIRE.

Specification of Letters Patent.

Patented J an. 8, 1918.

Application filed March 8, 1917. Serial No. 153,370.

To all whom it may concern:

Be it known that I, MATT A. KoMrULA, a citizen of the United States,residing at Calumet, in the county of Houghton and State of Michigan,have invented certain new and useful Improvements in Implements forTwisting Wire, of which the following is a specification.

My invention relates to improvements in implements adapted for wrappinga section of wire around the end portion of a section of flexible hoseor the like, having a rigid pipe projecting therein, for securelybinding the hose to the pipe, and twisting the ends of the wire, in ahighly expeditious and convenient manner.

An important object of the invention is to provide a device of the abovementioned character, which is of simple construction, inexpensive tomanufacture, strong and durable.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In mines, it is customary to drive reciprocatory hammers and the like bycompressed air, such compressed air being ordinarily fed through an ironpipe, terminating within the mine, near the hammer. A flexible hose isconnected with the hammer and secured to the pipe by having the pipeprojecting into its opposite end. This end of the hose is clamped to thepipe by a binding wire, extending therearound and having its endstwisted together.

I have found that considerable time is often lost in binding or clampingthe hose to the iron pipe, and my invention provides means for doingthis work in a highly expeditious and convenient manner.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

Figure 1 is an edge elevation of a device embodying the invention,

Fig. 2 is a similar view of the opposite edge thereof,

Fig. 3 is a side elevation of the device,

Fig. 4 is a similar view of the opposite side thereof,

Fig. 5 is an end elevation of the same,

Figs. 6 and 7 are side elevations of the device, illustrating thedifferent steps in the use of the same, when twisting the wire, and,

Fig. 8 is a side elevation of the work having the wire twistedthereabout.

In the drawings, wherein for the purpose of illustration is shown apreferred embodiment of my invention, the numerals 10 and 11 designatethe coacting handles of the tongs, carrying heads or disks 12 and 13.Thesedisks are pivotally connected at their centers by means of a boltor rivet 14.

The disk 12 is provided upon the forward side of its periphery with agroove or depression 15, starting at a point near its forward end andextending rearwardly and increasing in depth, with a laterally extendingflange 16, guarding the other side thereof. The free end of the groove15 discharges into a lateral opening 17, passing through the outer faceof the disk and this opening has a cutting edge 18. The disk 12 isprovided with a binding post or pin 19, rigidly secured to its outerface, at a point arranged near and spaced from the opening 17. The disk12 is provided upon its opposite side with an opening 20, having acutting edge 21, for a purpose to be described.

The coacting disk 13 is provided upon its periphery with a groove 22,starting from a point arranged near the forward end thereof, andextending rearwardly and increasing in depth, with a laterally extendingflange 24, guarding the outer side thereof. The groove 22 leads into alateral opening 25, passing through the outer face of the disk. Theopening 25 has a cutting edge 26. The disk 13 is provided upon itsopposite side with an opening 27 having a cutting edge 28, for a purposeto be described. The disk 13 is provided with a pair of binding posts orpins 25, as shown.

In the operation of the device, the wire 29 is passed about the work 30and one end thereof arranged within the groove 15, carried through theopening 17, and wrapped about or secured to the binding post 19. Theother end portion of the wire is arranged within the groove 22, carriedthrough the opening 26, wrapped about or secured to the binding posts25. -As shown in Fig. 6, the coacting handles 10 and 11 are suitablyopened, thus placing the desired tension upon the wire, prior to theturning movement of the device, whereby the wire is twisted, asindicated in Fig. 7. After this twisting operation, the wire is loosenedfrom the binding posts and the coacting handles are further moved to anopen position so that the opening 17 is moved into registration with theopening 27 and the opening 25 into registration with the open ing 21.The ends of the wire are then passed within these registering openingsand the coacting handles moved to the closed position, the cutting edgesof the opening serving as shears to cut the wire.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as, a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the sub- 7 joined claim.

prising a pair of pivoted coacting disks provided upon the forwardportions of their peripheries with grooves having their rear ends incommunication with'lateral openings passing through the inner and outersides of the disks, each disk being provided upon its edge opposite itsfirst named opening with a second opening to coact with the first namedopening of the other disk in cutting wire, a device carried by the outerside of each disk to secure the wire thereto, and handles carried by thedisks for turning them upon their pivots.

In testimony whereof I aflix my signature in presence of two witnesses.
